Additional Operating Information:
dBm reference = 50
Ω
Range boundaries are at voltage points, dBm levels are approximate.
dBm = 10 log (
Power

),
0.22361V across 50
Ω
= 1 mW or 0 dBm
Minimum output: 300

Frequency uncertainty:
±
0.01%
Frequency resolution: 11,999 counts to 1.1999 MHz, 119 counts to 30 MHz.
Overload protection: A short circuit on the wideband output will not result in damage. After settling time,
normal operation is restored upon removal.
